java中stack(栈)的使用代码实例

package com.lanhuigu.java.ListTest;
import java.util.Stack;
public class StackTest {
	public static void main(String[] args) {
		Stack<String> staffs = new Stack<String>();
		// 入栈顺序: a,b,c,d,e 
		staffs.push("a");
		staffs.push("b");
		staffs.push("c");
		staffs.push("d");
		staffs.push("e");
		// 出栈顺序: e,d,c,b,a 
		while( !staffs.isEmpty()) {
			System.out.print(staffs.pop() + " ");
		}
	}
}
